WESTERN Bulldogs defender Easton Wood has suffered a hamstring injury at training on Thursday, just one day after re-signing with the club until the end of 2018. 

The club described his latest setback as a minor hamstring injury that could sideline him for only one week.

Wood signed a one-year extension at the end of last season so both he and the Bulldogs could ensure his body could hold up to the rigours of AFL football. 

The 25-year-old battled persistent hamstring injuries early in his career, with a serious hamstring tear restricting him to five games in 2013. 

He played a career-high 18 games last year before a broken hand ended his season in round 20. 

Wood has undergone a biomechanical assessment of his running and focused on building strength at the top of his hamstrings in an effort to get past the soft-tissue problems.

He had impressed in the first two rounds of the season attacking off half-back under new coach Luke Beveridge, racking up 20 possessions against Richmond in round two.
